Two stars that are bond together by gravity and orbit a common center of mass are known as
a. meteroids
b. constellation
c. galaxies
d. binary stars

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

they should be similar or the same

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

amplitude

hope this
